Use the TEXT function. To see the help, use:
help text
In your case:
z = 100;
y=get(gca,'ylim');
h=plot([z z],y,'-r');
text(z,mean(y),'z = 100') % If text is too close to line, use z+inc.

inc is just an increment to add to the z. So if your xlim is [99 101], then and increment could be .1. If your xlim is is [0 1000], perhaps a larger increment would work - perhaps 1 or 2. I might even try to make the increment a function of xlim, say diff(xlim)/20 or whatever.
